A remote device, separate from the pump, contains a second CKU; this remote device can be another CKU, a point-of-sale terminal, a fuel pump device, or a site controller. A wired connection links the fuel pump device to the first CKU, and an unsecured connection links the first CKU to the second CKU. The first CKU has a processor with a secure authentication module, programmed to encrypt consumer payment information from the fuel pump device. The second CKU decrypts this information for the remote device. A tamper sensor (e.g., open door, motion, light, or echo-cavitation) detects tampering and, if triggered, disables the fuel pump device.
4. The system of claim 1 , wherein the first CKU further comprises a memory.

A wired connection links the fuel pump device to the first CKU, and an unsecured connection links the first CKU to the second CKU. The first CKU has a processor with a secure authentication module, programmed to encrypt consumer payment information from the fuel pump device. The second CKU decrypts this information for the remote device. A tamper sensor (e.g., open door, motion, light, or echo-cavitation) detects tampering and, if triggered, disables the fuel pump device.
5. The system of claim 4 , wherein the memory retains a log comprising the sensor information from said tamper sensor.
This secure system for fuel pump transactions includes a fuel pump with a housing, a tamper sensor, a fuel pump device, and a first Cryptographically Keyed Unit (CKU) all within the housing. The first CKU additionally comprises a memory, which retains a log of the sensor information generated by the tamper sensor. A remote device, separate from the pump, contains a second CKU. A wired connection links the fuel pump device to the first CKU, and an unsecured connection links the first CKU to the second CKU. The first CKU has a processor with a secure authentication module, programmed to encrypt consumer payment information from the fuel pump device. The second CKU decrypts this information for the remote device. A tamper sensor (e.g., open door, motion, light, or echo-cavitation) detects tampering and, if triggered, disables the fuel pump device.
6. The system of claim 1 , wherein the output information comprises at least one of consumer payment information or consumer identify information.
